IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent No. 141,801, dated August12, 1873 application filed May 20, 1873.

To all whom it may concern: v

Be it known that I, WILLIAM D. LINDSLEY, of Wathena, in the county ofDoniphan and State of Kansas, have invented a new and Improved FlameExtinguisher for Lamps; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing forming part of this specification, in which-Figure 1 is a side elevation. Fig. 2 is a side Fig. 3 is a detail viewof extinguisher.

The invention consists in making a very durable and compact joint ofboth spring and extinguisher, with the movable arm of the latter, bybending and riveting the end of the arm.

In the drawing, A is the lamp-top, having the wick-tube B. O O are theextinguishers, which may be closed over the top of the tube; and D D arethe arms which hold the snuffers, that have handles d d, by which theyare turned. The arms are bent and pivoted in the snbjacent bearings a aof a plate, A. E E are springs, placed on the inside of snuffers G G,and with one end projecting toward the tube B. One end of arm D is firstbent at right angles, passed through the snuffers G and through thespring E, and then staved up on the end to form a rivet-head. In therear of the arm D is an apertured brace, F, through which the end of armpasses before it is turned.

The mode of attaching the spring on the inside of the extinguishers,prevents it from be ing in the way, and renders it much less liable tobe fractured, while the mode of securing it with the extinguisher by theriveted end of arm D greatly simplifies the construction of these parts,renders them much more compact, and cheapens the manufacture.

By using the brace F thearm D is menforced, and not so liable to breakat its junction with the extinguishers.

The application of the plate A beneath the lamp-top A makes asecure'bearing for the arms, and one that is entirely out of the way.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The arm D, having the end turned at right angles, passed through bothspring and extinguisher, and riveted down in front, as and for thepurpose set forth.

WM. D. LINDSLEY.
